Charged black hole surrounded by a galactic halo in de Sitter universe
R. A. Konoplya, Z. Stuchlík, A. Zhidenko
Assuming a sufficiently general form for the matter distribution function of a galactic halo, we have derived solutions to the Einstein-Maxwell equations describing a charged black…
Transition from Regular Black Holes to Wormholes in Covariant Effective Quantum Gravity: Scattering, Quasinormal Modes, and Hawking Radiation
R. A. Konoplya, O. S. Stashko
Utilizing the Hamiltonian constraints approach, a quantum-corrected solution has been derived \cite{Zhang:2024ney}, which describes either a regular black hole or a traversable wor…
How general is the strong cosmic censorship bound for quasinormal modes?
R. A. Konoplya, A. Zhidenko
Hod's proposal claims that the least damped quasinormal mode of a black hole must have the imaginary part smaller than half of the surface gravity at the event horizon. The Strong…
Are eikonal quasinormal modes linked to the unstable circular null geodesics?
R. A. Konoplya, Z. Stuchlík
In Phys. Rev. D 79, 064016 (2009) it was claimed that quasinormal modes which any stationary, spherically symmetric and asymptotically flat black hole emits in the eikonal regime a…
Quasinormal modes and a new instability of Einstein-Gauss-Bonnet black holes in the de Sitter world
M. A. Cuyubamba, R. A. Konoplya, A. Zhidenko
Analysis of time-domain profiles for gravitational perturbations shows that Gauss-Bonnet black holes in a de Sitter world possess a new kind of dynamical instability which does not…
Quasi-Normal Modes of Brane-Localised Standard Model Fields II: Kerr Black Holes
P. Kanti, R. A. Konoplya, A. Zhidenko
This paper presents a comprehensive study of the fundamental quasinormal modes of all Standard Model fields propagating on a brane embedded in a higher-dimensional rotating black h…
